Environmental value is essential to the survival and development of humans. Environmental value and its importance are being emphasized, and related disputes are being expanded. The concept of green logistics is understood to be the same as that of the environment. As a way to preserve nature and engage in sustainable development, green logistics includes all logistical activities for protecting nature and minimizing or reducing behaviors that harm the environment for all processes, including using and reusing products and abolishing the search for resources by final users. All areas of human activity, such as the political, economic, social, and cultural sectors, strive to protect and preserve the environment and nature. In particular, the preservation of the environment shall be stressed in the economic activities that produce various products and expand the value added, and similarly for the social aspects. Green (environment) logistics aims to protect the environment and expand the prevention of environmental destruction and minimization on Earth. Some important cases and experiences that were introduced and applied in major countries are summarized. This research reviewed previous studies and the concepts of green logistics, including at ports, which represent a key sector of logistical activities. In this paper, air and water pollution at Incheon Port were investigated, and alternatives and system figures related to improving environmental logistics regarding three dimensions-country, company, and civil society-are recommended.

In this case study, we analyzed the STEAM lessons conducted by secondary science teachers in the perspective of the CHAT. Two science teachers at high schools in Seoul participated in this study. All of the teaching-learning materials were collected before lessons, and their lessons were observed and videotaped. We also observed the atmospheres in both school offices and classrooms. Semi-structured interviews were conducted before and after their lessons. All the data collected were categorized according to the elements of the activity system and analyzed by using the constant comparative method. The analyses of the results revealed that both teachers did not consider the student-centered self-directed activities in their STEAM lessons, but that they differed in the subject element such as teacher's professionalism on STEAM. Various elements of the activity system such as environmental characteristics of the school and policies about the STEAM influenced the performance of their STEAM lessons. Contradictions in the elements of the activity system brought about various changes. Successful experiences of the STEAM lessons by complex effects of the elements positively influenced their performances on their STEAM lessons. Based on these results, we have made some suggestions for the establishment of the STEAM in secondary schools.

This study is to identify the concept of action from the critical science perspective and to explore the agency of home economics teachers for the purpose of teacher education. The context and various characteristics of home economics teacher' agency were identified in terms of philosophy and teacher education. The results of the study indicates, first, the concept of action refers to an activity of individuals involving one's own intentions, and include the ability to reveal a unique identity that aims to reach a set purpose and decision, and this can be identified by mutual meaning in the public sphere. Second, teacher agency is influenced by a teacher's professional experiences and cultural and structural aspects, and it can create an environment which can promote self-directed and cooperative relationships among individuals and communities. Therefore, home economics teachers should be able to reasonably judge, contemplate, and act through reflections on the circumstances and consequences in which their agency is exercised. Third, home economics teachers can reflect and think critically about the values, roles, and sense of purpose of home economics education based on agency. Teachers should focus on the process of achieving their agency rather than on completing it, and they can continuously develop it through a perceived shared understanding among teachers. Therefore, the conceptualization of the agency of home economics teachers is to understand the practice revealed in a teacher's actions. This requires environmental support in school settings because it acts as a mechanism for strengthening the thinking and reflection of teachers through the creation of interactive environments in which professional knowledge and experiences can be shared.

This study aims to analyze difficulties that pre-service elementary teachers experience in investigating the life cycle of a common cabbage butterfly in person. As difficulties they face during the process of this research, they pointed out collecting eggs, observing molting, creating environments for a breeding cage, feeding, building a breeding cage, and making butterfly specimens. Out of all the environmental difficulties related to their school fields, they pointed out a difficulty of time management most of all, followed by placing a breeding cage in the classroom and the lack of microscopes for observation. In regard to difficulties related to their evaluations on students' activities, they found it difficult to evaluate students' activity with the life cycle of an insect in the aspect of knowledge and even to set evaluation criteria. Besides, many of them responded that it would be appropriate to evaluate a research on the life cycle of an insect through a portfolio or an observation journal. In regard to difficulties in terms of teachers' knowledge, they found it difficult to understand insect molting, metamorphoses, complete metamorphoses, incomplete metamorphoses, the structure of an insect body, and how to distinguish a female insect from a male one. In regard to the application of class models, they knew it is important for students to have various experiences through direct observation, so the experience-based learning model was proper for the process of observing the life cycle of a common cabbage butterfly. However, they found it difficult for students to observe each stage of the life cycle in person.

This study aimed at analyzing stress factors of radiography students may experience during their clinical training, and thus at providing assistance in improving efficiency and quality of clinical training. As for the method of study, a questionnaire survey was conducted targeting radiography students from five universities in Busan and Gyeongsangnam-do regions who had clinical training experiences. The result of the survey showed that, among five stress factors, environmental factor was the highest source of stress, followed by ideals, values, roles and activity. In addition, it was found that the level of stress experienced during clinical training was higher than the level of stress in daily life. If the stress of clinical training can be reduced based on the results of this study, it will not only contribute to improving students' level of satisfaction with clinical training, but also enhance the quality of clinical training.

This paper aims to examine the ways in which project-based organizations (PBOs) are embedded in social networks and geographical clustering in the case of TV drama industry. PBOs refer to a variety of temporary organizational forms for the performance of tasks as to integrate diverse and specialized intellectual resources. PEOs as a flexible and innovative mode of organizing knowledge resources are becoming increasingly worthy of attention in emerging the creative economy. Evidence from interviews with core persons of PEOs like producers, directors, and writers reveals that the key operational mechanism of the project form of organization is based on the highly socialized networks via individual's reputation and past experiences. In other words, the project activity in TV drama is embedded in networks which are socially constructed. Also the geographical clustering plays an important role in PBOs and project practices in TV drama are constructed around a high degree of spatial clustering. PBOs are clustering in Kang-nam and Yeouido, where are located in independent production companies and broadcasting stations. It means that the project formation in TV drama requires geographically-clustered networks of human resources, and socially, culturally and geographically embedded latent networks of interpersonal relationships are a necessary condition of POBs in the TV drama industry.

Prior studies have shown positive effects of outdoor activities on the elderly's physical, mental and social health. 'Active aging' and 'age-friendly' neighborhood can be created by modifying the experiences and perceptions of the outdoor environment. This study aims to investigate the outdoor activities of the elderly living in a low-income elderly concentrated area and their perception of the neighborhood environment. We also explored the context of interactions between the facilitators and inhibitors of outdoor activities on the basis of temporal, spatial, and social conditions. We used a mixed method approach by collecting two different types of qualitative GIS data : observation maps of the main places and individual cognitive maps with in-depth interviews. The observational map analysis indicated that the preferred places and activity patterns differ by age, gender, and size of the group. The cognitive map and interviews demonstrated that the elderly's activity goals and perception of the landscape differ by places such as forests, parks, streams, open-spaces, vegetable gardens, and alleys. The elderly's desire for outdoor activities can be better fulfilled when their front doors and alleys are well-connected to an open-sight pleasant space. Familiarity is an important factor for the elderly, therefore it is important to remove the psychological and physical barriers by increasing the legibility and accessibility of places. In addition, social interactions and conflicts can have a significant influence on the elderly's occupation of space in the neighborhood environment.
